Magnification immersion radiography: better soft tissue visualization in the hands.

We have combined microfocal magnification with immersion radiography and mammographic technique to produce superb soft tissue and bone detail in the hand using a single PA exposure. The lateral projections provide excellent demonstration of the flexor and extensor tendons and joint capsules. This method has proved valuable as the primary radiologic examination in the evaluation of soft tissue lesions in the hands, particularly in patients suspected of having rheumatoid arthritis.
